Abstract: 1,135,512. Toothed gearing; hydraulic drive transmission. J. BINNS. 16 Nov., 1966 [21 July, 1966], No. 51264/66. Headings F2C and F2Q. [Also in Division B3] To eliminate backlash from a saddle or carriage feed mechanism for a machine tool such as a lathe, including a fixed rack 8 meshed by two spaced apart pinions A, B rotatably mounted on the carriage 16 and connected by separate gear trains 36, 38, 40 and 42, 44, 46 to oppositely handed helical gears 34, 32 secured on an axially floating drive shaft 30, an axial force proportional to the torque loading on the mechanism is applied to the shaft 30 by an hydraulic ram 60. This tends to rotate the pinions A, B in opposite senses to take up backlash. The shaft 30 is driven through gears 26, 28 by a reversible hydraulic motor 22 connected by lines 84, 86, a stop valve 102, and lines 106, 104 to a variable displacement pump 94 driven by an electric motor 96. Lines 76, 78 branching from the lines 84, 86 supply the twin piston single-acting ram 60 with fluid at drive circuit pressures, the latter being proportional to the torque load on the gearing. A control unit 100 monitors motor 22 speed or position. Pressure relief valves 122, 124, 126, 128 give overload protection for the gearing and hydraulic system. A variable displacement pump 110 driven by an electric motor 114 pressurizes and tops up the main hydraulic drive circuit via a restrictor 116, a heat exchanger 112 and a line 134, and also provides servo pressure to the stop valve 102 and to the displacement control 136 of the pump 94, and counterpressure, through a line 138, to the ram 60.

Title: Thin film transistors
Inventor: YUDASAKA ICHIO
IPC: H01L29/786
Filed: 2000-01-07
Abstract: The TFT 10 comprises a channel region 15, a gate electrode 14, a gate insulating film 12, a source region 16 and a drain region 17 formed in a polycrystal semiconductor film 100. In the channel region 15, a recombination center 150 is formed for capturing a small number of carriers (holes) by implanting impurities such as inert-gas, metals, Group III elements, Group IV elements and Group V elements into a predetermined region of the channel region 15, or by defects generated in the channel region due to the introduction of these impurities. The bipolar transistor type behaviour of a conventional thin film transistor in which excessive drain current for high drain voltages occurs is prevented by the recombination centre. The impurities, such as phosphorus ions are implanted through a recess 141 in the gate electrode to form the recombination centre.

Title: Image signal decoder and image signal display system compensating for inter-frame motion
Inventor: YONEYAMA AKIRA
IPC: H04N19/85
Filed: 2000-06-01
Abstract: On input coded data, variable length decoding is performed, (101) and motion vector information extracted. The motion vector information is transmitted to a threshold value determination section (112) and a predetermined threshold value and the value of the motion vector information are compared. Where the motion vector information has a value of the threshold value or more, the system determines whether it is necessary to control the interframe motion or not. When the control is necessary because the interframe motion is large, the control signal generation section (113) generates a control signal to suspend the decoding by the varibale length decoding section and thereby reduce a frame rate.

Abstract: A saturation instruction contains field with bit length n (example 10), source register and destination register for simultaneously performing saturation of a plurality of elements A,B of a source register Rm to n-bit length values in a destination register Rd. The saturation may be signed (-2<SP>(n-1)</SP> to 2<SP>(n-1)</SP>) or unsigned (0 to 2<SP>n</SP>-1) and will clamp and flag values outside these ranges.

Abstract: A video communication unit (405) includes a video input (415) for receiving an un-watermarked video or image signal transmission having a number of video or image frames (110, 120, 130, 140), wherein each video or image frame includes a number of bit planes, the video input (415) being operably coupled to a processor (410). The processor (410) splits at least one bit plane (116) from each of at least two video or image frames (205, 210) into a first and second portion. The processor combines (235, 242, 232, 245) a second portion of the at least one bit plane of a first frame with a first portion of the at least one bit plane of a second frame to apply a watermark bit to the video or image signal transmission. A video communication system and methods of detecting a tampered area and visually labelling the tampered area are described. This enables fraudulent tampering of images and video to be detected, and the location of such tampering to be revealed to users of the material.
